CVE-2024-21627
PrestaShop some attribute not escaped in Validate::isCleanHTML method
Impact
### Description Some event attributes are not detected by the isCleanHTML method ### Impact Some modules using the isCleanHTML method could be vulnerable to xss ### Patches 8.1.3, 1.7.8.11 ### Workarounds The best workaround is to use the `HTMLPurifier` library to sanitize html input coming from users. The library is already available as a dependency in the PrestaShop project. Beware though that in legacy object models, fields of `HTML` type will call `isCleanHTML`. ### Reporters Reported by Antonio Russo (@Antonio-R1 on GitHub) and Antonio Rocco Spataro (@antoniospataro on GitHub).
